Key Concepts

Genetic Variability

Genetic variability describes the range of genetic differences within a population. In endangered species, reduced genetic variability can be a significant concern because it limits the ability of the species to adapt to environmental changes, thereby increasing the vulnerability of the population to extinction.

Extinction Risk

Extinction risk is the probability that a species will become extinct in a defined time period. Species that are in imminent danger throughout a significant part or their entire range are considered to be at high extinction risk, prompting urgent conservation actions.

Endangered Species

An endangered species is one that faces a high risk of extinction in the near future due to factors such as significant population declines, habitat loss, or environmental changes. This status is a critical indicator that proactive conservation measures are needed to prevent the species from disappearing entirely.

Population Reduction

Population reduction refers to the severe decrease in the number of individuals in a species. When a species experiences such a decline, it becomes more vulnerable to environmental fluctuations, diseases, and other external pressures, which can lead to an increased risk of extinction.
